Wind turbine has no blades, creates no noise

Check out this interesting wind turbine that relies on boundary layers instead of blades so that it can generate power without making a sound. Patented by Solar Aero, this turbine known as the Fuller turbine was modeled after the 1913 Tesla steam turbine, where it is fully enclosed and virtually silent, doing away with traditional drawbacks of bladed turbines such as noise, radar interference, visual pollution and wildlife injuries. The turbine will most likely come with a cut-in speed of about 3.5 knots and an optimum speed of around 20 knots, offering near transparency to radar microwave transmissions using proper construction materials and techniques. Currently in the prototype stage, the world waits with bated breath for working units to be released in varying sizes in due time.
